Abstract: In an exemplary embodiment, a communication device, such as a ra-diotelephone (100), has within its housing (106) an apparatus for electrically coupling an electricoacoustic transducer (201), such as an earpiece, to ratio-telephone circuitry. The apparatus comprises resilient conductive means, for example conductive barrel springs (213-216), abutting both the conductive contacts on the earpiece (241, 243) and the corresponding conductive con-tacts on a printed circuit substrate (205, 208 and 206, 207). A bracket (211) manually attached to the printed circuit substrate (203) positions the con-ductive barrel springs (213-216) while they are compressed between the ear-piece (201) and the printed circuit substrate (203) during the assembly of the radiotelephone (100). A plurality of barrel springs (213-216) are used to pro-vide redundant electrical coupling and stability for the earpiece (201). The apparatus advantageously provides for improved manufacturability and convenient replaceability of the earpiece (201).

Title: Atm network topology auto discovery method
Inventor: SUZUKI HIROSHI
IPC: H04L12/70
Filed: 1995-07-18
Granted: 2000-06-13
Abstract: A network topology discovery method automatically recognizes the physical connection relationships of each ATM switch and each ATM terminal within an ATM network. Each ATM switch and ATM terminal mutually exchanges, by ILMI protocol, port identifiers that identify every ATM port of the ATM switch or ATM terminal as well as network addresses of network management agents that manage the ATM switch and the ATM terminal, to neighboring ATM switches and ATM terminals that are directly connected to its ports. Each ATM switch and ATM terminal stores tables for each of its ATM ports that include port identifiers which indicate the identities of connected ports as wall as the network addresses of the network management agents that manage the neighboring ATM switches and ATM terminals. The ATM switches or ATM terminals automatically recognize the local connection relationships with its neighboring ATM switches or ATM terminals, using a network management system, by accessing connection information and then automatically recognizing the physical connection relationships of each ATM switch and each ATM terminal. The network management system recognizes the configuration within an ATM network, whether the network management system is inside or outside the ATM network, including when a router or existing LAN coexists with the ATM network. The identities of ports connected to each port are recognized, when a plurality of links exist between ATM switches, without requiring the assignment of a respective one of its ATM network management agents to each ATM switch.    Interfaces between ATM switches as well as between an ATM switch and an ATM terminal are also automatically identified.

Mounted on a movable element (not shown) there is a resonant circuit (10) comprising a coil (14) and capacitor (17) that can magnetically couple with the windings (13 and 15). When the circuit (10) is excited it induces currents in the windings (13 and 15) that are dependent upon the position of the circuit (10) within a period Ts of the windings (13 and 15). An excitation and processing unit (11) is provided to energise the circuit (10) and to process the signals induced in the windings (13 and 15).

Abstract: A swing-away hopper tee assembly for attachment at the discharge end of a hopper. The hopper tee assembly has a mounting frame for attachment at the discharge opening of the hopper. The mounting frame associates with alignment pins on a bottom side for alignment of a valve housing. The valve housing is positioned below the mounting frame and receives the alignment pins. The valve housing cooperates with alignment pins of the hopper tee. The hopper tee is pivotally attached to the mounting frame by a pair of adjustable pivot arms and extends below the valve housing. The hopper tee has a camming handle and hook assembly on the front side. The hooks extend upward and engage slots on the mounting frame. The camming handle can be locked into place securing the hooks in the mounting frame and effectively securing the valve housing between the hopper tee and mounting frame. The handle can be rotated over the center to lift the hooks away from the mounting frame and allow the hopper tee to swing away from the valve housing. The valve housing then can be removed and the assembly effectively cleaned.

Abstract: The invention concerns a method of generating electrical energy from biomass which is produced in a biomass-production module. The biomass is gassified in a reformer module to form a hydrogenous crude gas from which a purified fuel gas with a high hydrogen content is formed in a crude gas processing module, electrical energy being generated from the purified fuel gas in a converter module. In this case, biomass with low sulphur and chlorine contents is produced by suitable fertilizing of plants. The reformer module operates with at least one allothermic reformer, the dwell time of the biomass and/or crude gas in the reformer and the pressure and temperature therein being set so that alkali compounds can be removed from the reformer with any ash produced. Tar is gassified in the reformer to form carbon monoxides and hydrogen. A purified fuel gas containing fewer than 1 % carbon monoxides is produced in the crude gas processing module. The purified fuel gas is converted into electric current by at least one PEM fuel cell, the operating temperature of the fuel cell, the water content of the purified fuel gas and the pressure of the purified fuel gas being adapted to one another so as to produce an optimum flow density.
